Abstract

<PICT:0972727/C1/1> <PICT:0972727/C1/2> <PICT:0972727/C1/3> A glass panel 1 which exhibits optical effects, and particularly for use as a cover panel for light sources, has a fire finish on both surfaces and projections consisting of bulges 2 formed by blowing directly out of the glass in the heated state, each bulge having in its protruding portion particularly at its apex 3 on one side, a reduced wall thickness to promote the diffusion of light. As shown in Fig. 5, a mould frame 11, for receiving molten glass, is placed on a base-plate 8 having a plurality of grooves 9 communicating through ducts 10 with a source of compressed air. A plate-like mould 12 having a grid structure is secured on the frame 11 and is preferably formed from flat iron bars 13 placed on edge. Compressed air blown through grooves 9 causes the molten glass to form the bulges 2 between the bars 13, the wall thickness being reduced at the apices 3 by selection of appropriate air pressure for the initial thickness of glass. In a similar construction, Fig. 7, not shown, the frame 11 and mould 12 are enclosed in a chamber which is evacuated to assist formation of the bulges. As shown in Fig. 8, the mould 12 is replaced by a moulding roller comprising a spindle 16 with threaded ends 17 on which guide discs 23 are engaged to hold between them moulding discs 19 separated by spacers 18 and end cutting discs 24 for trimming the longitudinal edges of the panel. The spacers 18 have transverse recesses 20 into which moulding cross-bars 21 are fitted and which form a grid with the discs 19, into which the glass is bulged by air through grooves 9 and ducts 10. The roller may be provided with at least one knife extending transversely between the cutting discs 24 to cut the glass into panels of equal lengths as the roller is passed through the frame 11. In a modification of this embodiment, the roller is rotatably mounted in a stationary position and the base 8 and frame 11 are moved thereunder. In a further modification, the movable roller may control valves supplying the compressed air to the grooves 9. The glass used may be transparent or translucent and may be coloured.
